A man cleared of all charges after his arm was broken in a "disturbing" arrest has said he thought the officers involved behaved with excessive force.

Shane Dwyer, 48, was cleared of resisting police today after Magistrate Jennifer Atkinson raised concerns about the level of force used to restrain him in his Eastlakes apartment block in Sydney last December.

"What I saw in that DVD was quite, quite disturbing," she told the court.

Constables Ben Vizzone and Brett Hanna had a body camera rolling when they arrived at the front door of Mr Dwyer's home following allegations he had been seen with knife and had also yelled threats at a female neighbour which included "all Russians should be killed".

Moments after he was told he was under arrest Mr Dwyer attempted to shut the door, but the officers barged him and pinned him to the ground.

The confronting vision, obtained by 9NEWS, also depicts his elbow being twisted in the wrong direction.

One officer was heard to say, "that's what you get for shutting the door on us mate."

"Throwing me to the ground like that and breaking my arm."

Ms Toomey said she had no doubt, after 15 years in her profession, that there were "officers who think they can be violent with absolute impunity".

Constable Vizzone was among those in court as Magistrate Atkinson dismissed those charges and announced she would be referring the case to the Law Enforcement Conduct Commission, which investigates allegations of wrongdoing in the police force.
